Bananas normally never need pesticides to produce. I don't know where you got your information, but it's not correct, I'm afraid. Emile Frison is one of the world's leading banana researchers, and according to Dr. Frison: www.futureharvest.org/pdf/banana.pdf [] Bananas are threatened by the rapidly spreading fungus Black Sigatoka that has been undermining banana production for the past three decades. It has reached almost every banana-growing region in the world and typically reduces yield by 30 to 50 percent. Other diseases and pests that cripple yields include a soil fungus, parasitic worms, weevils, and viruses such as the Banana Streak Virus, which lurks inside the banana genome itself. Commercial growers can afford and rely extensively on chemical fungicides, often spraying their crops 50 times per year—the equivalent of spraying nearly once per week, which is about 10 times the average for intensive agriculture in industrialized countries. Chemical inputs account for 27 percent of the production cost of export bananas. Agricultural chemicals used on bananas for diseases and pests have harmed the health of plantation workers and the environment. “If we can devise resistant banana varieties, we could possibly do away with fungicides and pesticides all together,” said Frison. “In addition, resistant strains are essential for small-holder farmers, who cannot afford the expensive chemicals to begin with. When Black Sigatoka strikes, farmers can do little more than watch their plants die. Increased hunger can swiftly follow.” [] www.futureharvest.org/pdf/banana.pdf EV I've additionally heard the domestic banana really is endangered because its own genetic material has narrowed to a couple strains developed for large size & toughness in shipping & physical apeparance (not so much for flavor) while wild bananas have vanished with loss of habitat. Some worry that eventually corn will will follow for the same reasons. Without careful preservation of a series of wild forms, the selectively bred & genetically altered crops eventually meet a disease that takes them down. Without the original seed stocks which can restore genetic strength, that's the end of a staple crop. At best there'll be massive if temporary crop die-offs equivalent of the Great Potato Famine. -paghat the ratgirl -- "Of what are you afraid, my child?" inquired the kindly teacher. "Oh, sir!

I've seen them by the hundreds in my apples; I don't think they will attack a perfect apple, but once yellow jackets or birds or something make a little hole in the apple, the ladybugs go after it. They enlarge the hole, which then attracts more ladybugs. Interesting. I hadn't heard of this. But I did find some puzzling evidence on my plums. The first time I saw them years ago, I thought they were ladybugs that had somehow died just before becoming fully formed adults. I thought they were must resting on the fruit to morph and had died. Then, when everyone brought up plum curculios as a big probelm on plums, I checked some sites to see what they looked like, and though my bugs don't look like the adult PC, I thought they might be a pre-adult stage not shown. Now I'm wondering again. They are a big problem for grape growers because when they get inside the grapes, they stink up the juice when the grapes are crushed and they can easily ruin the wine. At least with a ladybug infested apple, you can see them. The stupid thing is that the asian ladybugs were imported as beneficials in vast numbers. Now, thanks to them, native ladybugs have been extirpated almost everywhere the asian has been introduced. Good intention, very bad idea. I get the chills whenever I hear about another insect they want to release to combat some alien that was accidentally imported and has no natural enemies. Importing alien bugs to battle alien bugs or plants is a dumb idea at best. New studies show that the main advantage that alien imports (insects, mollusks and plants) have is that their usual parasites don't exist here. Whereas they may be preyed upon by a dozen parasites on their home turf, here there are just a few at most. BTW, they also bite people. This I know! :-D The first few times I transported ladybug larvae to the rose buffet by hand, the little buggers bit me. I transported them in plastic cups after that. They're now everywhere so I don't have to move them around. I didn't introduce them here. They were very well established when I moved here. EV |
